Thanks guys for the investigation, you were exactly true: we always resize SVGs on import, that was done to keep all imported graphics nearly the same size, as was requested when importing from a certain source. You can disable it through the registry key: HKCU\SOFTWARE\Xara\SVGFilter\6.1\scale - set this to 0 to avoid resizing on load. On the next release we'll come up with a smarter decision on keeping original SVG dimensions vs resizing in only certain conditions.
